THREAD-GUIDE SUPPORT FOR SPINNING R TWISTING MACHINES.-;

Specification of Letters Patent.

Application filed September 10, 1908, Serial No. 452,460. RenewedJanuary 21, 1915. Serial No. 3,642.

. To all whom '52, may concern and claimed in patent granted to me July.25

1905, No. 7 95,769, and in patent granted Clarence A. Pierce, April 1,1905, No.

To this end the invention consists of the parts and combinations ofparts hereinafter described and illustrated in the accompanying drawing,forming part of this application for patent, in which,

Figure 1 is a plan View of a thread guide support constructed to embodymy invention. Fig. 2 is a side elevation thereof. Fig.

:3 is a front elevation thereof on the line :3-3 of Fig. 1. Fig. 4 is across sectional elevation. Fig. 5 is a perspective view of the threadguide clamp. Figs. 6 and 7 are l :a plan and front illustration of amodification, and Fig. 8 is a perspective view of the clamp used in themodification shown in Figs. 6 and 7.

In my Reissue Patent No. 12,362 is shown a form of thread guide supportwhich has gone into extensive use which support is :made out of sheetmetal having a base or supporting part depending from which are sideflanges and a front flange and which support is hinged to the doflingrail by a plurality of fingers extending from its rear edge whichintermesh with a plurality of fingers carried by the rail to form ahinge joint.

One object of the invention is to improve and simplify this hinge jointand to this end I provide the support with a single smooth car at itsrear end which is bent around a wire or pintle carried by the rail or bya strip secured thereto. This provides an improved smooth hinge oint'.

In my Patent No. 795,769, a means is shown whereby the thread guide ispivoted at one point and clamped at another thus providing a pivotingsidewise adjustment and an in and out adjustment and at two pointsupport for the thread guide.

In said patent to Pierce No. 786,380 a clamp is shown which can beadjusted laterally parallel to the thread guide and in which the threadguide can be adjusted in and out. A second object of the presentinvention 1s to combine in one structure, the good points of both thesepatents. I provide a clamp which can be adjusted laterally on thesupport and which is held from turning thereon, which clamp has a twopoint engagement with the shank of the thread guide pressing the same tothe underneath side of the support thereby combining in one clampingmeans the advantages of sidewise adjustment of the clamp in linesparallel with the shank of the thread guide and of a two pointengagement of the clamp with the thread guide.

Further advantages tending to simplify and improve the parts will behereinafter described.

Referring to the drawing and in detail A designates the back or doffingrail which may be made of wood, as shown in Fig. 1 or out of metal asshown in Fig. 2 and secured to the front face thereof, is a sheet metalstrip B which has ears 1010 projecting therefrom which carry and supporta pin or shaft 11.

C designates the thread guide support, which is pressed or struck out ofsheet metal so as to have depending side flanges 1212, a front flange 13and a projecting rear ear 14.. The thread guide support is secured inplace by bending the single ear 14 at the rear edge thereof around thepin 11 to form a hinge joint. By this construction a hinge is providedwith less joints which prevents the accumulation of lint and whichaffords a smooth surface for cleaning.

Formed in the top surface of the thread guide support is a hole 16 and adepressed section 17 which forms a projection on the underneath surfaceof the thread guide support which holds the clamp D parallel to thefront flange of the support C and in engagement with the front flange. Ascrew or bolt 18 having a non-circular or square section 19 is insertedin the hole 16 and is provided with a nut 20 to engage the threadPatented Apr. 6, 1915.

To this end i guide clamp D. This threadguideclamp D is struck out ofsheet metal so as to have two upwardly extending sides 21 which H mayhave triangular notches therein to engage the shank rtion of the threadguide T at two points which is preferably made triangular in. crosssection. The thread-guide clamp is made slightly arched in shape, asillustrated in F ig. 8. Other shapes maybe given to the thread guide andnotches.

The thread guide support C has aslot 22 through its front flange 18so'that the thread guide T may be moved sidewise. The clamp -D has aslot 23 through which the screw 18 extends so that the clamp may bemoved sidewise so that by loosening the nut on the 7 bolt 18 aconsiderable degree of sidewise adjustment is obtained in the guide Tand its' clamp D which slides between-the projection 17 and thefront'fian ge 13 of the thread guide support. The projection 17 thusforms a means for preventing the clamp from twisting and'keeps the clampin engagement With the front flange. By this arrangement not only isconsiderable lateral or sidewise. adjustment for the thread guide Tprovided, but the thread'guide can also be adjus'ted in and out in theclamp. Thetwo flanges 21 21 of the clamp form two bearingfpoints forholding the thread guide T and by using this'two point bearingengagement and holding the clamp from twisting asimple and rigidclamping means is pro vided. v, v

In the modification shown in Figs. 6, 7 and v8, the front flange 13 iscut down so as to form a reduced flange 1 30 and the front flange. 21'of the clamp D engages the'front side of the flange 130, the clamp D inthis modifi eationhaving upwardly turned ears 132 with spaces 131131between the same and the flange 21, in which spaces the flange 130 fits.The ears 132132,-in this construction, thus comprise a means for holdingthe thread-guide clamp in engagement with said front flange and thuscorrespond in function with the depressed section" 17 of the first.described modification. In both constructions, the clamp can beadjustedalong the flange, but as it is kept in engagement therewith, itwill be held from turning and will be guided in parallel positions'inits lateral adjustments. This is important, as the thread-guides oftenreceive a blow or push Copies of this patent may be obtained for thusout of adjustment. i r

which maytend to move them side-.Wise and It will be seenthat in bothconstructions the clamp and hence the thread guide can beadjustedlaterally orparallel to the front flange a considerabledistance, and the tWo point engagement of the clamp with the threadguide preserved. By these improvements, the cost of themanufactureisreduced and the article is simplified. y

The proportion of the parts herein shown and described may be varied bya skilled mechanic without departing from thescope' of the invention,asexpressed in the claims.

Having thu's'de's'cribedmy invention what 1. In a threadboard mechanism,th'e'com-' bination of a thread-guide support having a front, outsidedownwardly depending guide, comprising a thread-guide clamp for holdingthe thread-guide in fixedposition,
